Basically I have level 1 data at start and when user tap on any cell I am fetching data for that selected index. and I want to show that data once I got it from server and same goes on for next tap. how I can achieve that with this lib?

This works for me:

func treeViewSelectedNodeChildren(for treeViewNodeItem: AnyObject) -> [AnyObject] {
        ...
                    self.loadOptions(idParent) { arrItems in
                        self.arrItems = arrItems
                        self.ciTreeView!.reloadData()
                        DispatchQueue.main.asyncAfter(deadline: .now() + 0.2) {
                            self.ciTreeView?.tableView(self.ciTreeView!, didSelectRowAt: self.indexSelected)
                        }
                    }
     ...
 }
